Garmin Venu 4 45mm vs Vivoactive 6
Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 47mm, the Vivoactive 6 is the safer pick — it stays proportionate down to roughly 44mm, where the Venu 4 45mm starts to hang over the edge. Above 47mm both sit cleanly, and the Venu 4 45mm gives you more presence.
The Venu 4 45mm wears larger than the Vivoactive 6 (45mm vs 42.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Vivoactive 6 is the slimmer of the two (10.9mm vs 12.5mm), so it slides under a cuff more easily.
On the wrist the Vivoactive 6 feels lighter (23g vs 38g, case only).
The Venu 4 45mm is thinner than 70% of the 45mm watches we track and the Vivoactive 6 than 84% of the 42mm ones — so both wear flatter than their widths suggest.
The Venu 4 45mm is 2.8mm wider, 2.8mm longer, 1.6mm thicker and 15g heavier than the Vivoactive 6. Both are circular.

Watch Fit Tool
For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.
Garmin Venu 4 45mm
Case 45.0mm · Lug-to-lug 45.0mm · Thickness 12.5mm · 38g
Balanced Fit
45mm on a 55mm wrist
Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 45mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
- 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.
